SIGNAL-OPERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 693,109, dated February 11, 1902.

Application filed October 24, 1900. Serial No. 34,140. (No model.)

To all whom it may concern: 7

Be it known that I, CLARENCE W. COLE- MAN, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Signal-Operating Apparatus, of which the following is a specification. Y

My invention relates to signals, and especially to devices for operating signals.

It has for its object to provide a signal-operating apparatus which will operate one or two signals, which will operate two signals from acommon motor or source of power, and willoperate them independently of each other.

It also has for its object to simplify and improve signal-operating apparatus and to make it certain in operation.

It consists of the novel devices and combinations herein set forth.

Although not limited to such devices, my improvement is of particular value in railway automatic signaling apparatus, and in the accompanyingdrawings, forming part of this specification, and in which similar reference characters in the different figures represent corresponding parts, I have shown the preferred form of my improved devices as connected with automatic railway-signals and with the usual home and distant signals com monly employed, although it will be understood that my devices may be used with other than home and distant signals.

Referring to the specific form or embodiment of my invention shown in the drawings, Figure 1 is a View of a pair of home and distant signals mounted upon a standard and showing the method of connection with my improved signal-operating devices. Fig. 2 is a side and detail view of certain parts of my improved signal-operating devices. Fig. 3 is a plan of the said parts. Fig. 4 is a side view of the same parts and some of their connections viewed from the opposite side from that of Fig. 2. Fig. 5 is a detail of parts of the signal-operating apparatus. Fig. 6 is a front view of the driving parts of my improved apparatus, and Fig. 7 is a diagrammatic view showing one system of circuits by means of which my improved devices can be controlled automatically bya train on the track.

Referring now to the specific form orembodlment shown in the drawings, 1 represents a home signal, and 2 a distant signal, arranged inapairand mounted in the usual way upon a standard 3. As shown, the signals are normally held at safety each through an actuating-rod 4, moved as will hereinafter be described. The signals are counterweighted at 5 in the usual manner, so that when left free to move they will move to danger. Two signalsare operated from a common motor 6. Power is transmitted from the motor through connections between it and the two signals, so as to operate the signals independently of each other. To accomplish this, I provide in the connections between the motor and the signals a common operating part, which in the form shown in the drawings consists of gear-wheel 7, and between this and one of the signals-as shown,the homesignal-I arrange two latches adapted to be engaged with or be disconnected from each other to connect the motor with or disconnect it from the said home signal. One of these latchesis mounted on the gear-wheel 7, and consists of swinging latch 8, pivoted at 9 to the wheel. The other latch consists in the form shown of the armature-lever 10 of magnet 11. (Shown in Fig. 2.) Armature-lever 10 is pivoted at 12 to a revolving arm 13, loosely mounted upon shaft 14., the same shaft as that upon which gear 7 is mounted. Arm 13 carries with it magnet 11 and its connections, and at its left end, as viewed in Fig. 2, is connected witha rod 15, which is connected by a lever 16, back of the one shown in Fig. 1, with operating-rod 4 of home signal 1. The pivotal connections between rod 15 and lever 18 are made by means of alink15. (Shown in dotted lines in Figs. 2, 4, and 6.) Operating-rode of distant signal 2 is similarly operated bya rod 15 and an additional lever. (Shown as 16 in Fig. 1.)

" Latch 10 is provided at its right end, viewed as shown in Fig. 2, with a too or projection 17, which is adapted to engage with the square foot of swinging latch 8, as shown in Fig. 2. A spring 18 presses latch 8 toward latch 10,

causing a yielding engagement with toe 17 of '1 has been moved to safety position.

the latch. Gear 7 is driven from the motor through shaft 19, pinion 20, gear 21, shaft 22, and gear 23 of the same shaft. It is always driven in the same direction and causes gear 7 to rotate in the direction of the arrow shown in Figs. 2 and 4. Latches 10 and 8 are held in operative engagement with each other whenever magnet 11 is energized. In this position of the parts if gear 7 be driven by motor 6 revolving arm 13 will be rotated on its axis and the home signal 1 will be moved to safety. In order to insure that swinging latch 8 will be held in engagement with latch 10, I preferably mount upon one side of the frame-work a cam-surface 24, which will positively hold latch 8 against latch 10 until signal By the time this has been done toe 17 has come opposite and has been caught by the teeth of rack 25. This rack acts as a catch for holding the latch 10, and with it the signal, in its set position. Rack 25 is pressed by spring 26, so as to engage with toe 17. In order to positively withdraw latch 8 from engagement with toe 17 of latch 10,1 preferably mount upon the framework of the machine a camsurface 27, which is arranged to lie in the path I of a pin 28 projecting from the side of latch 8. As pin 28 engages cam-surface 27 latch 8 is positively withdrawn from engagement with the toe of latch 10. By the movement of the parts thus described home signal 1 has been moved to its safety position and is caught and held there, and at the same time the engagement between it and gear7is broken, so that the latter is free to continue its rotation. It will be understood that this position of home signal 1 takes place only when magnet 11 is energized and only when the motor itself is energized. As long as magnet 11 remains denergized the toe 17 of catch 10 simply moves out of the way of catch 8 should gear 7 be rotating. When it is desired to release home signal 1 from its safety position, as held there by catch 25, magnet 11 is denergized, whereupon armature 10 is released and too 17 slips off from the teeth of rack 25, arm 13 and all it carries returns to its normal position, and signal 1 returnsto danger, position, all through action of counterweight 5. After home signal 1 has been moved to its safety position, as above described, danger-signal 2 can be moved to its safety position by the further rotation of gear 7' by the following-described means: Between gear 7 and distant signal 2 I also preferably place a latch for connecting them together or for disconnecting them. In the form shown it consists of a similar armature-lever 29, pivoted at 30 upon a revolving arm 31, loosely mounted, upon shaft 14 and operated by a magnet 32, all as shown in Fig. 4. a too 33, which projects into the path of aprojection 34 from one side of gear-wheel 7, as shown in Fig. 4. As gear-wheel 7 rotates projection 34 strikes toe 33, and if magnet 32 is denergized simply idly pushes it out of the It also has way Without moving arm 31. If magnet 32, however, is energized, latch 29 is operatively held and the rotation of gear 7 rotates arm 31, which carries with it magnet 32 and rod 15. Rod 15 is connected with rod 4 bymeans of lever 16, pivoted in the casing. This additional lever is inserted in order to give the proper direction of motion to rod 4 to move distant signal 2 to safety. When latch 29 is released through the devitalizing of magnet 32, distant signal 2 returns to danger.

In practice I prefer to place two latches S on gear-wheel 7, arranged diametrically opposite each other, and also to place on the other face of gear-wheel 7 two projections 34, also arranged diametrically opposite each other and so placed on the periphery of the gear-wheel that each projection 34 is ninety degrees awayfrom each latch 8. In this way the gear 7 when operatively connected with the signals will first move the home signal to safety, where it will be caught and held by rack 25, and then gear 7 will begin to move distant signal 2 to safety, provided, of course, the, proper magnets are energized. A half-turn of gear 7 will thus move both signals to their set position-as here shown, the safety position. When gear 7 has thus made a half-revolution, I prefer to use means for automatically deenergizing the motor, and thus stopping the movement of gear 7at this point. As such means are well known they are not here shown and described, exceptdiagrammatically. The stoppage of wheel '7 causes projection 34 to hold toe 33 in the position to which it has been moved, thusholding distant signal 2 in its set or safety position, and this continues until magnet 32 is decnergized, and toe 33 consequently released from projection 34. \Vhen the motor and the proper magnet or magnets are again energized, gear 7 is again rotated in the same direction another half-revolution, and so on. The motor thus drives the gear 7 always in the same direction. A pawl 35, engaging with ratchet-wheel 36 on shaft 22, prevents backward rotation of these parts.

Any suitable means may be employed for controllingthe latches; but I prefer to use automatic means and'preferably magnets controlled bya train upon the track. Any suitable system of circuits may be employed for this purpose. In Fig; 7 I show a diagrammatic view of one system of circuits which I have found useful in connection with myimproved devices, and I will now proceed to describe the system as there shown.

The track is divided into blocks 37 38 39 40 in, the usual manner, each insulated from adjoining blocks and provided, as shown, with batteries 41, 42, and 43. Each track-circuit is provided with a relay. As shown, they are 44, 45, and 46. Each of.-these relays controls a magnet 11 through circuit-controllers 47,

48, and 49, respectively. Each magnet 11 controls a latch 10 for home signal 1, as has been already described. This armature is shown in the diagram of Fig. 7. With no train on the track the track-circuits 'are normally closed, circuit-controllers 47, 48, and 49 are held in their closed position, and relays 11 are energized, thus holding home signall normally at safety. The circuit through magnet 11say of block 39is as follows: battery 50, wire 51, circuit-controller 48, wire 52, magnet 11, wire 53, main-line wire 5%, back to battery. Whenatrain enters upona blockfor example, block 39-it deenergizes magnet 45 and with it magnet 11, sending the home signal 1 to danger. Each home signal 1 mechanically and automatically controls three difierent sets of contact-points. As shown in Fig. 7, these are shown as connected with operating-rod 40f home signal 1 and consist of contact-points 55 to enable the home signal in its movement to control the distant signal 2 of the same pair, contact-points 56 to enable it to control the distant signal of the pair of signals in the rear of the home signal in question, and, lastly, contact-points 57 to control the motor-circuit. When the home signal stands at safety, contact-points 55 56 are closed and contact-points 57 are open. As the home signal goes to danger contactpoints 55 and 56 are broken, thus sending to danger or keeping at danger the distant signal of the same pair and the distant signal in the rear, and contact-points 57 are closed, closing that break in the motor-circuit. Each of these circuits will now be separately described. The circuit through contact 55 is as follows: from battery of block 40 to wire 58, circuit-controller 49, wires 52 59, contact-points 56 of home signal 1 of block 40, wire 60, contact-points of home signal 1 of block 39, wire 61, magnet 32 of distant signal 2 of block 39, wires 62 63, and line-wire 54 back to battery. The break at contact-points 55 made by home signal 1 of block 39 going to danger thus insures its corresponding distant signal 2 going to danger or staying atdanger if already there. The circuit through contact-points 56 of home signal 1 of block 39 is as follows: battery 50 of block 39, wire 51, circuitcontroller 48, wires 52 59, contact-points 56, wire 60, contact-points 55 of home signal 1 of block 38, wire 61, magnet 32 of distant signal 2 of block 38, wires 62 63 to line-wire 54, to battery. This insures that the distant signal 2 in the rear of the home signal in question, or, in other words, the distant signal 2 of block 38 will go to danger, or if already at danger will stay at danger when home signal 1 of block 3.9 goes to danger. The motor-circuit through contacts 57 is as follows: bat-' tery 64 of block 39, wire 65, motor 6, wire 66, contact-points 57, wire 67, armature 68 of magnet 11 of block 39, wire 69, back to battery. WVhen home signal 1 moves to danger, the break at 57 in this circuit is closed. As long as the train remains on block 39, however, the motor will not be energized, owing to the break in magnet 11 at controller 48.

cuit at 57 and closing the contacts 55 and 56,

permitting distant signal 2 in the rear to go to safety. The contacts at 71 and 57 are not shown in detail in the diagram Fig. 7, their presence only being indicated in that diagram. These contacts are made in the usual manner, and are of course arranged so that they are not broken as the signals move to safety until the safety position is reached. Such construction is so well known that it is not shown in detail in the drawings. As long as train remains on block 40, however, distant signal 2 of block 39 cannot go to safety because of the break at contactpoints 56 made by home signal 1 of block 40 being at danger.

When the train moves off from the block 40, these contact-points are closed and the distant signal 2 of block 39 can then go to safety. The motor 6 of this block is energized for this purpose through a branch of the motor-circuit from battery 6%, which runs from wire 66 through wire 70, contact-points 71, secured'to operating-rod 4 of distant signal 2 in question, wire 72, circuit-controller 73 of magnet 32 of the said distant signal, wire 74, wire 69, to battery. Contact-points 71 are normally broken when danger-signal 2 is at safety and are closed when it goes to danger. By means of my improved devices both signals form a pair and can be operated independently of each other and by a single motor. My improved devices are simple in construction and efficient and certain in operation. By means of them the driving parts can always be driven in the same direction.

In operating a single signal with my device the swinging latch 8, magnet 11, arm 13, and connections will not be used, but those parts which have been above described as being used to operate the distant signal will in such case be employed. in the clear position by pawl 35 engaging with ratchet-wheel 36 on shaft 22, preventing gear 7 from rotating backward. Upon the magnets becoming deenergized the signal will go to danger, and when the magnets and motor are again energized the next lug on gear-wheel 7 will carry the signal to clear position, and so on. Any suitable number of lugs may be employed upon the side of gear-wheel. 7 for this purpose, thus allowing one-fourth or one-fifth or other fractional turn of gear 7 to put the signal in clear povsition.

The signal will be held the set position into which signals are moved loo devices shown in the drawings could also be made without departing from my invention, 1

term signals is used in the claims or in the statement of invention herein it is used in a sense broad enough to include any other or similar objects which are to be moved into set position and to which my invention is applicable.
